What do prokaryotes and eukaryotes have in commmon?
DNA, proteins, plasma membrane
What is the name of the family of DNA binding proteins that function to package DNA into chromatin?
histones are the proteins that compact and order DNA into subunits in the first step of the making of chromatin
How is protein organized in a chromosome?
Chromosomes are mostly DNA not proteins, but there are small proteins that "package" and protect the DNA. These proteins are somewhat different in prokaryotes and eukaryotes:Prokaryotes do not possess nuclei. Instead, their DNA is organized into a structure called the nucleoid. This structure is, however, dynamic and is maintained and remodeled by the actions of a range of histone-like proteins, which associate with the bacterial chromosome. In archaea, the DNA in chromosomes is even more organized, with the DNA packaged within structures similar to eukaryotic nucleosomes.In the nuclear chromosomes of eukaryotes, the uncondensed DNA exists in a semi-ordered structure, where it is wrapped around histones (structural proteins), forming a composite material called chromatin.
How is the DNA in prokaryotes different from from the DNA in a eukaryotes?
dna in eukaryotes is located in the nucleus
What area of a gene carries the code used to make a protein?
The coding region. In eukaryotes this is often divided into a number of discreet regions of DNA called exons.
What is histon?
A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)

Chromatin in case of prokaryotes is made up of?
Chromatin is made of histone proteins. It is used for DNA packing. The DNA winds around it like little spools. In eukaryotes, this occurs in the cell nucleus. Prokaryotes do not have a cell nucleus although their DNA does wrap around small structures which only resemble the histone proteins of eukaryotes.

The coding region. In eukaryotes this is often divided into a number of discreet regions of DNA called exons.
What three organelles help make and transport proteins?
The four organelles in eukaryotes are: - Nucleus: contains the DNA which is synthezised - Ribosomes:synthesizes the proteins - Rough endoplasmic reticulum: transports the proteins - Golgi apparatus/complex/body: where the proteins are chemically modified and then sent out to different parts of the cell.
What kind of cell has linear DNA?
All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
How is the DNA in a prokaryote different from the DNA in a eukaryotes?
DNA in prokaryotic cells is usually circular while DNA in eukaryotes is usually linear. DNA in prokaryotes usually has fewer portions that dont code for something while eukaryotes usually have quite a bit of DNA sections that dont code for anything. The number of actual base pairs (the units that makeup DNA) that makeup eukaryotes is usually quite a bit more than the number in prokaryotic DNA.
